Hello,
I am setting up a CNC control setup for a denford branded sherline mill. I am unable to get the steppers to move with Mach 3.
Here is my setup:
PC-to-route m2 BOB board:

And gecko 201 stepper drivers
http://www.geckodrive.com/gecko/images/cms_files/G201%20REV-16%20MANUAL.pdf
I am using 2Amp 24v stepper motors made by Sanyo Denki
http://m.findic.us/103h7126-5740-price-en-YL4K08OnQ.html#2
I am running Windows xp on a Sony vaio desktop with parallel port.
So far I have confirmed that my bob is talking to Mach 3 by triggering limit switch inputs but am unable to get it to move the steppers.
As far as I can tell my wiring is correct based upon those data-sheets and the steppers are powered as they have holding torque when the drivers are on.
Thank you for any help!
Here are some photos of the setup:

In Mach3 Config / Ports & Pins / Motor Outputs try changing both Step and Direction signals to Active Low.
Do you have +5V connected to the Gecko drive ?
Do you have the charge pump enabled on pin 17 ? (Config / Ports & Pins / Outputs)
Can you reset (get Mach3 out of) Estop ?
Tweakie.

I hope that the motor voltage is not the 24vdc you posted. If it is these motors will have no torque at any useful speed. You need motors rated much lower voltage, maybe 2 volts.

enabling the charge pump did the trick!!!
thank you so much! now on to hooking up the other motors.
yea I'm pretty sure they are 24vdc but they shouldn't need much torque as they are on a little baby mill. They were stock from the company Denford that sold the mill.
